Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| ORCPIN_PRIVATE_KEY | yes | yes | Private key (0x + 64 hex) of a dedicated, low-balance Base wallet holding a few dollars of USDC. Used only to sign gasless x402 payment authorizations; never transmitted. A door report costs about $50, so fund for what you intend to buy. |
| ORCPIN_TOOLSETS | — | — | Optional comma-separated subset of tools to expose: "defi" (chain + endpoint-reliability tools) and/or "trading" (trade-log calculators). Default: all ten paid tools. The free directory tool is always exposed; the ledger tools (statement, door report) are exposed regardless of this setting. |
| X402_NETWORK | — | — | x402 network id. Default eip155:8453 (Base mainnet). |
